In the era of digital architecture, parametric design plays a fundamental role in the generative architectural design process. The most important of its benefits are that it allows a visual representation of the design process, a designer interaction during the construction of the parametric model using visual codes, the representation of steps sequentially and logically, in addition to the ability to adapt the model according to the client’s requirements and the designer's wishes, and to generate various design solutions and alternatives for the same model.
Parametric Typology is an approach that combines typological design with computational parametric techniques in order to produce various designs that belong to a specific building type. The research problem revolves around the application of parametric Typology to generat initial designs for local housing. Previous studies have proposed different approaches in the implementation of parametric typology to designs ranging from urban scale, individual buildings, to building elements. The research presented a theoretical framework, drawn from previous studies, to clarify the concepts and techniques of parametric typology method. The methodology was applied to build parametric model using a visual algorithm in grasshopper software. Prototypes for single-family housing had been generated as a functional type that occupies the largest space in cities; in addition there is a huge demand for it. As a result of the study, initial models were implemented with variety of parametric in terms of the placement of activities and the number of spaces.
